I guess that the 10 sales they would have gotten from Japan wasn't enough incentive to get in trouble with CERO.
Goddamn you people are dumb, I'm sure that M$$$$ isn't for region locking, but you apparently can't put a Z game up and have it downloadable in Japan, probably some sort of law. Maybe region-locking was overkill, but for all we know that had to happen. PSN can't be compared because there aren't any games that would be banned, and their video store is region locked too.
This is the future, like it or not. Years ago you could view anything from any site, these days all sorts of shit is IP locked. There are a lot of streaming videos that you can't view unless you're in the States, some music sites won't work, some sites actually ban certain country IPs. I definitely don't agree with it, but people will always want to control the Internet. I'm sure we'll be looking at the "good old days" when you could look at anything on the Internet without the majority of content being IP restricted.
